Substitution means substituting the value of one variable (in terms of the other variable) In this example, let's rewrite equation 2 as: m = 3n + 16. Thus, we can write m in terms of n, and substitute it in equation 1. So equation 1 becomes : 7(3n+16) + n = 46. Now, this equation has only one variable, n, so you can find n from it. Once you find n, put it in the previous equation to find m.

so would it be 21n+112+n=46 22n+112=46 22n+112-112=46-112 22n=-66 n=-3 m=3(-3)+16 m=-9+16 m=7
